1994 Walld Koenig 2 Melanerpes formicivorus Lambert HNHR (4 February) An excellent showing. These 2 trees are quite replete. Red alert! There are 300 acorns stored in the Arnold Schwarzenegger tree! Who are these birds? Is there a separate group here again? Time to get on Wendy and Jennifer's butts. Also note: last year's (Lambut) nest hole has fallen. 11 April 1035. Still some stores at Swartznegger; birds are calling on the side of the hill and thus could belong anywhere. Up at Lamburt itself there are plenty of stores but none in any holes. 15 April 1130. Bird in hole in traditional nest tree: 2 eggs translucent but dirty. Measured them: ① 25.4 × 20.3 ② 24.2 × (9.8 (egg ② probably laid 1st.) 20 April 1110. Checked hole: 5 eggs. New ones are ③ 25.3 × 20.1 ④ 25.3 × 20.1 ⑤ 24.3 × 18.7 Hence, the dirtiness of the eggs makes a fairly nice chronological gradient, from egg ②-①-(③-④)-⑤. Presumably egg ② (FED) was 14 April, while egg ⑤ (LED) was 18 April. 20 May 1645. Banded & bled the 4 babies. Stores still remaining. 25 May Not only are there still stores at Swartz, they have a nest in the old nest tree with very old kits that Jeremy found a few days ago! 18 July 1850. (Lots of stores remaining.
